Use of the safety function
Contents of this chapter
This chapter describes the use of the safety function with factory default settings.
Activating the safety function
1. Push the emergency stop button [S61]. The emergency stop is activated and the button
locks in the “ON” (open) position.
Depending on the stop category, either AAA1 FSO STO request (stop category 0) or
AAA3 FSO SS1 request (stop category 1) is shown.
When the emergency stop function is completed, the following indications are shown:
• the emergency stop reset button indicator light [S62] on the cabinet door is on,
indicating that it is now possible to reset the emergency stop function.
• AA90 FSO stop completed is indicated.
If configured with parameter 31.22 STO indication run/stop, an indication for Safe torque
off is shown when the drive STO is activated.
The indications that the FSO module generates are configurable. For more information, see
chapter Parameter settings (page 43) in this manual and chapter Fault tracing in the FSO
module user’s manual.
Note: The indication lamp comes on also when the FSO module has completed a stop
function after fault situations. Also, the indication lamp comes on momentarily when the
drive is started.
